Consider This

Few would consider that there was facial confusion during the 1960s between Mike Nichols (left), a famous director, producer, actor, and comedian (1931-2014), and the lesser-known William Redfield, an actor in theater, film, radio, and television (1927-1976). The multi-talented actors were from the same era, and both died in NYC. The photo comparison may solve any confusion. 

Likewise, few would compare these two actors, and not brothers. From left to right, introvert Robert Young (1907-98) and extrovert Richard Denning (1914-98). They had a facial resemblance at certain ages; both were 6' tall and died the same year. Denning was in radio, television plus numerous low-budget films. Those of a certain age may remember him as the Governor from his recurring role on the original Hawaii Five-O televison series. Young was an A-list and second banana actor in both high and lower-budget films and had huge success with two successful television series.
